OT: Lowering a task priority on Windows

Our installation of Grid Control is progressing very slowly due to the
JAVAW.exe process from the OUI consuming 80-90% of the cpu. Anybody
know if there would be any negative effects of right clicking the
process and then setting its priority to "low".

I agree with Peter. It might be worthwhile asking your Windows Admins to install the SYSINTERNALS (Google for Mark Russinovich) process monitor, and/or process explorer. This is now owned by Microsoft.

You might then be able to find what it is doing, and what log files it has open. Check those log files for more clues/evidence, and work outwards from there.
